The crowdsourced bathymetry approach : - Pre-qualified measurement systems (HydroBall / HydroBox) - Local people from the communities (Inuits) - Automatic data processing and dissemination More reactive and cost effective than - Survey teams from the South - Conventional hydrographic tools

Pre-qualifiedsingle-beamsystem:HydroBall™
A robust shell of spherical shape (13kg – 40cm diam) which contains : - Echosounder (depth measurement) - GNSS receiver (position) - Inclinometer (roll and pitch)
* Autonomous, easy to use
Pre-qualifiedblack-boxsystems
HydroBox: - Installation on opportunity vessels
- includes same components as the HydroBall except for :
sonar component which comes directly from the vessel.
* HydroBox is equipped with a GNSS L1/L2 receiver capable of logging raw data.
HydroBoxasasingle-beamsystem
* Measurement of lever arm between GNSS and sonar needed to geo-reference the soundings.

How? Crowd sourced bathymetry with members of Inuit communities Why? Maritime traffic = >>>>>>>>>> Population = >>>>>>>>>> Safety of navigation = IMPORTANT Cost of data acquisition = <<<<<<<<<< Contribution to the development of Inuit communities
